Wastewater

Project

A deep trunk sewer and drop shaft re-routing combined flows away from an overloaded waterfront interceptor.

Deep gravity sewer, drop shaft and odour control for a legacy combined system.

Construction ran beneath a congested, contamination-sensitive corridor, demanding strict environmental control and continuous public monitoring.

Scope of work

  • Tunnels & Underground Engineering
  • Construction Management
  • Geohazards
Hoffman Tunnels provided tunnel and underground design, engineering and construction-phase support.
